VALVE.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed February 1, 1915. serial No. 5,459.

T0 all whom 'it may concern y Be it known that I, JOHN D. JONES, a citizen of the United States, residing at Talla Walla, in the county of l/Valla Walla and State of l/Vashington, have invented certain new and useful Improvements in Valves, of which the following is a specification.

The present invention relates to improvements in valves and on my former Patent No. 1,113,789, dated Gctober 13, 1914, and has for its objects:

First, the provision of a valve having means for seating the valve within its casing when the same is both in its open and closed positions;

Second, the provision of means for moving the valve from its seat, during its movements from open to closed position or from closed to open position, thereby preventing all wearing of the parts thereof, and greatly facilitating the quick and easy operation of the same;

Third, the provision of means for preventing the entrance of dirt or foreign objects between the adjacent walls of the valve and casing and the valve and its seat;

Fourth, the provision of a valve wherein all operating parts are disposed without the casing, thereby rendering them readily accessible, and easily replaced or repaired.

Fifth, the provision of a valve, which will be comparatively simple and inexpensive to manufacture, reliable and eflicient in use and readily operated. Y

With the above and other objects in view, the present invention resides in the novel features of construction, formations, combinations and arrangements of parts, to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which: j

Figure 1 is a side elevation ofy a valve constructed in accordance with the present invention;

Fig. 2 is a longitudinal sectional view on the line II-II of Fig. 4 with the valve in its intermediate position;

Fig. 3 is a transverse sectional view taken on the line III-III of Fig. 1; and

Fig. 4 is a similar view, taken on the line IV-IV of Fig. 1. f

Referring to the accompanying one sheet of drawing, by corresponding characters of reference throughout the several views, the

numeral 5, designates in dotted lines a portion of a boiler or the like, having an opening 6 therein, to which my improved valve 7 is applied.

This valve 7 comprises a valve casing 8 having a gradually tapered seat or bore 9 therein, and a flange 10, formed upon its inner or larger end, which engages the boiler 5, around the before mentioned opening 6. The iange 10, has one or more openings 11 provided therein for the reception of suitable fastening elements (not shown) whereby the valve 7 can be rigidly secured to the boiler If desireda suitable Packing, such as shown at 12, can be interposed between the boiler 5 and flange 10, to prevent leakage. The valve casing 8, has an opening 13 formed in one side thereof which is preferably surrounded by an internally screwy threaded nipple 14, to which can be attached any suitable object such as a drain pipe or the like (not shown).

A cup valve 15 is located within the casing 8 and is externally tapered as shown to conform to the tapered bore 9 of the casing 8. The inner end of thevalve 15, is open and communicates with the interior of the boiler 5, through the opening 6. The inner end of the casing 8 is channeled as at 16, to receive a thimble 17, which is provided with an outwardly extending annular iange 18, designed to fit within the inner open end of the valve 15, i thereby preventingl the entrance of -dirt or other foreign particles between the adjacent outer walls of the valve 15, and inner wall of the casing 8.

A stem 19 extends axially from the outer closed end of the valve 15, through an opening 2O,` formed in the outer closed end 21 of the casing 8, which is shown in Fig.A 2 of the drawing. There is a slight play or clearance between the opposite ends of the valve 15 and thimble 17, and closed end 21of the casing 8, which permits of a slightlongitudinal movement of the valve 15 for a purpose to be later explained.

Bosses 22 extend from` diametrically opposite points upon the end 21 of the casing 8, while extending around the outer edge of this end 21, are arcual ribs 23 having cam faces 24 which curve inwardly from the bosses 22 to intermediate points between ,the said bosses, which are spaced a correspondingdistance from the end of the casing 8. The opposite ends 0f the ribs 23 adjacent Y slightly larger in diameter than the stem 19 to permit the insertion of a bushing 28 therein, which is keyed as at 30, tothe said stem 19 in order that the same will be rotatable therewith. For the purpose of rotating the stem 19, the outer end thereof is made angular in cross-section as shown at 31, for engagement with a suitable tool or the like Y(not shown), by means of which the said stem 19 can be rotatedand the valve ymoved either from open to closed positionV orffrom closed to open position, as desired. Pins 32 project laterally from diametrically opposite points upon the sleeve 28 for insertion into the guiding slots and engagement with the cam faces 24 of the ribs 23, and cam faces 24 of the spider 25. When the-,valve 15 is in its open or closed position, the pins 32 engage the cam faces 24 and 24 at the portions of the ribs 23, and spider 25 adjacent the bosses 22. Upon the move-ment of the valve from open to closed position, or from closed to open. position, the pins 32 will pass to the thinnest portion of the cam faces 24, as shown in dotted lines in Fig. 4, thus moving the outer end of the valve 15 farther away from the inner side of the wallY 21, than when the valve is either in the open or closed position, as indicated in dotted lines in Fig. 2.

It will be apparent that during this movement there will be no friction between the outer face of the valve' 15 and its .bore or seat 9 to cause any wearing ofthe parts, and owing to the absence of rall fiction, the valve can be easily rotated without the `slightest exertion on the part ofthe operator. In order to further facilitate the easy operation of the valve 15, la thin filmof lu- `v bricant can be inserted between the adjacent surfacesof the valve 15 and bore or sear 9 in the casing 8.

To prevent the valve 15 from becoming yunseated or disturbed from its open or closed position, the cam surfaces 24, 24 on the vribs 23 and the spider 25 and adjacent to the bosses 22, are preferably in a straight line as shown at 33, so that each of the pins 32, is resting on a plane iiat surface and have no tendency to ride down or slide away from the extreme adjusted positions of the valve, should the boiler or section of apparatus to which the valve is attached Vbe subjected to vibration, knocking or jarring action.

lhile I have shown and described my Vpreferred valve construction, as being prois in position for use, and the internal sec-v tion of the valve 15 is under pressure of the water, steam or other fluid, said pressure will normally tend to force said valve 15 against its seater bore 9 or toward the closed end 21'of the casing 8 and either of the pins V32 connected to and movinO' with stem 19 will at all times,.bear against one of the cam faces 24, and hence Vthe valve 15,V could be slightly moved away from seat or bore 9V in the opening and closing of said valve as heretofore described, with only one Vpin 32 and one outer cam face 24, if so described.

.It will also be seen that the cam -faces 24 or 24 being on the outside can be readily machined or constructed, and put in position without necessitating the taking apart or removing the valve from the boiler or other appa 1atusl It'should be understood in this connection, that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims, without departing from the spirit or sacrition. Y

From the foregoing it will be manifest that a valve is provided, which fulfils all of the necessary requirements of such a deently of the casing and arranged adjacent to the cam formed on the casing, a valve stem extending from said valve through the end of the casing, a sleeve keyed to the valve stem and a pin extending from the sleeve and engaging the cams formedfinde-V pendently of the casing, whereby upon the rotation of the valve stem, the valve will be moved from and to its seat, during movement to and from its open or closed position.
